Skipped directly from XP to Windows 7, and every once in a while I run across something that makes me feel really juvenile. I was recently trying to pass a directory structure to an offsite developer who was having configuration issues so that they could compare their project structure to what was running on the server. So I requested access to the server, and mapped a drive. I grabbed a path to the directory from an email, and switched to a command prompt that I had been using to run iisreset commands while I make local deployment changes to some WCF services. I tried to change the directory from C:\Windows\System32\ to the mapped drive, but I kept getting "The system cannot find the drive specified."

Now I know it's been a while since I have messed around with the command prompt, but I was feeling really stupid. I know that if you type something like C:\> D: the drive should change to "D", I even googled the command. Well, silly me, I had been running the Command Prompt with elevated permissions, but since the drive had been mapped using my standard account, it was not visible to the elevated "administrator" permissions that I was running the command prompt under. I guess that the juxt of this was the fact that I had mapped as one "elevated" account (my normal login), then tried to access it using a separate "elevated" account (administrator). I don't really think of "administrator" being on the same permission level as my normal login, but in this case it may be.

If you have any other insights into permission issues like this, let me know.
